A friend where in which his/her personality is so conflictive to your own, that you can only stand to hang with or talk to once a week; someone you agreed to stay friends with after there was an issue between you two.

1. Me and James can't really hang out often. His sarcasm makes me want to kill him, but i guess I'm still his weekly friend...

2. After me and my Ex broke up we promised to be friends. Despite the fact I hate that bitch, we stay weekly friends just to keep that promise..
